Abstract

Trichoderma spp is a cosmopolitan ground fungus. Trichoderma is a soil saprophyte fungus is advantageous for plants. Several species of Trichoderma indicate having the ability as a bio-fertilizer so as to help plant growth. This research was conducted at the Laboratory of Faculty of Agriculture Faculty of University of Tanjungpura Pontianak for 7 months. The exploration is done from rhizosphere rice tidal rice which is considered fertile, less fertile and irrigation channel. Isolation using dilution casting method. Dilution rate is 10-1,10-2,10-3,10-4. Each Trichoderma isolate is tested for its ability as a biological fertilizer such as dissolving phosphate, dissolving potassium, degrading cellulose, producing IAA. Isolates classified as superior tested hypovirulen seed cucumber. Exploration results obtained by 38 isolates Trichoderma spp. Based on solvent test of phosphate isolate TRTS6 has the highest potential with solvent index of 72%. In subsequent tests Trichoderma was not found to dissolve K, degrade cellulose or produce IAA. Trichoderma spp species found from exploratory results include T. harzianum, T. auoreoviride, T. hamatum, T. psudokoningii T. koningii, T. koningii sp. Calculation of Disease Severity Index (DSI) in hypovirulent test 5 potential isolates inoculated on cucumber plant showed 0% value. Type of Trichoderma harzianum (TSTS6) is a recommended as a fungus that can be used as a bilogical fertilizer in dissolving phospate. Key words: Cosmopolitan, exploration, saprofit fungi, Trichoderma.

Abstract

Antraknosa merupakan penyakit penting pada cabai. Penyakit disebabkan oleh Colletotrichum sp. Pengendalian menggunakan agens hanyati adalah pilihan yang dapat digunakan untuk menggantikan penggunaaan fungisida kimia  sintetik. Penelitian ini bertujuan untuk mengkaji potensi kamir yang berasal dari filosfer buah cabai sebagai antagonis terhadap Colletotrichum sp. Penelitian ini meliputi eksplorasi kamir, isolasi Colletotrichum sp, uji antagonis, uji filtrat kamir terhadap Colletotrichum sp.. Kamir yang didapatkan dari filosfer buah cabai adalah sebanya 8 isolat, dan semuanya bersifat antagonis terhadap Colletotrichum sp, dengan kisaran antara 47% sampai dengan 53% Uji filtrat dilakukan menggunakan 3 isolat kamir dengan daya  antagonis lebih dari 50% yaitu : isolat Y3, Y6, dan Y8. Hasil uji filtrat kamir menunjukkan isolat Y3 dapat menghambat perkecambahan spora Colletotrichum sp, lebih besar dibandingkan dengan Isolat Y6 dan Y8 Kata kunci : agens hayati, fungisida kimia sintetik, uji filtrat

Abstract

 Blast is important disease of rice, and it caused by Pyricularia oryzae Cav. Synthetic fungicide in plant disease control may have negative impacts, so another alternative is needed. Yeast can used as a biocontrol agent. This research aims to investigate the potential of the yeast from leaf phyllosphere of rice paddy as biocontrol agent against P. oryzae. This research  was consisted of yeast exploration, isolation and filtrate antagonistic inhibition essay to P. oryzae, and yeast growth respon due to temperature. Ten isolates successfully obtained and tested as antagonist to P. oryzae. Five isolates, YLP05; YLP07; YLP08; YLP09; YLP10, have percentage inhibition more than 30% at 3 dai (day after incubation) dan more than 50% at 7 dai, but their filtrate had not shown any inhibition activity.  The five isolates had been formed colony on 1st day at 30°C.  Based on diameter and percentage of forming colony, the optimal temperature is different for each yeast isolates. Four isolates which can still grow at 20-40oC those are YPL05, YLP07, YLP09, and, YLP10.

Abstract

The production of black rice has decreased due to disease attacks. One way to improve rice resistance to disease is through the induction of mutations with gamma ray radiation. The purpose of this study is to evaluate the resistance of black rice induced by Co-60 by 0 Gy, 200 Gy and 300 Gy against disease. The research was conducted on BBI's land in Sungai Kakap Village, Kubu Raya Regency during one planting season, from October 2017 to April 2018. This research used a descriptive research method. Each treatment was observed as many as 50 rice plants, so that the total sample of observation is 150 plants. Observations were made 3 times, during vegetative, maximum vegetative, and generative periods. Disease identification is done in two ways which are macroscopic and microscopic. Assessment of the severity of the disease is guided by the guidebook. The results of the study found 4 diseases that attack black rice mutant plants, namely narrow brown spots, leaf and collar blast disease, fusarium disease, and midrib blight. Narrow brown spot disease, rice irradiated by 200 Gy is the most resistant with medium - rather resistant category. Leaf blast disease, rice that is not irradiated is most resistant with medium - rather resistant category. Panicle blast disease, rice irradiated by 200 Gy is most resistant with medium - resistant category. Keywords: Black rice, Cobalt-60 induction, disease scoring

Abstract

ABSTRACT               Chili pepper is one of horticultural crop that is quite important in Indonesia, it has a high economic value. Chili pepper plant productivity tends to fluctuate due to Fusarium wilt disease. This study aims to suppress the development of F. oxysporum disease in chili pepper plant using compost inoculated by Trichoderma spp. which de Decomposers and as biological agent. This research was conducted at Plant Disease Laboratory Faculty of Agriculture, University of Tanjungpura Pontianak. The experiment ased a randomized block design with 4 treatments: (Trichoderma spp. that has inoculated capability as dissolving cellulosa), (Trichoderma spp. Isolates as antagonists, and mixed two isolates Trichoderma spp. cellulose solvent with antagonist), and Control (EM4 as decomposer). This research is divided into two stages, on nursery and planting in the field. Trichoderma both as decomposer and antagonist treatment can suppress disease incidence at nursery 14.21%. composting give Trichoderma spp. has ent been able to stop the development Fusarium attacks on chili papper although the plant can still produce the fruit.

Abstract

Penelitian ini bertujuan untuk mempelajari daya adaptasi dan produksi beberapa varietas padi unggul baru pada sawah tadah hujan. Penelitian dilaksanakan di Desa Sungai Dungun Kecamatan Sungai Kunyit Kabupaten Mempawah Provinsi Kalimantan Barat berlangsung dari Desember 2015 sampai April 2016. Penelitian menggunakan rancangan acak kelompok. Perlakuan dalam penelitian terdiri dari 5 jenis varietas padi yakni: A (Inpari 30), B (Inpari 32), C (Inpari 33), D (IPB 3S) dan E (IPB 4S). Masing-masing perlakuan diulang sebanyak 5 kali dan setiap unit percobaanterdiri dari 5 tanaman sampel. Variabel yang diamati dalam penelitian ini meliputi: tinggi tanaman, jumlah anakan, persentase anakan produktif, panjang malai, bobot 1000 butir, jumlah gabah per malai, persentase gabah bernas per malai, jumlah biji total per rumpun, berat gabah per petakan. Hasil penelitian menunjukan bahwa pertumbuhan dan produksinya yang ditanam tidak optimal dibandingkan dengan deskripsinya yang disebabkan oleh faktor genetik dan factor lingkungan. Kendala yang dihadapi saat melakukan penelitian yaitu serangan hama tikus yang mengakibatkan 3 varietas padi tidak dapat dipanen.     Kata kunci: adaptasi, padi, pertumbuhan, produksi, sawah tadah hujan, varietas unggul baru.

Abstract

Nematoda patogen serangga (NPS) S. siamkayai merupakan salah satu musuh alami yang berpotensi sebagai agen pengendali hama tanaman. Penelitian dilaksanakan untuk menguji patogenesitas S. siamkayai isolat tanah podsolik merah kuning terhadap S. litura F. Penelitian dilakukan di Laboratorium Hama tumbuhan, Fakultas Pertanian, Universitas Tanjungpura Pontianak. Rancangan yang digunakan adalah acak lengkap (RAL) terdiri dari 4 perlakuan (150 Ji/ml, 300 Ji/ml, 600 Ji/ml dan 1200 Ji/ml) dengan 7 kali ulangan. Pengujian patogenesitas dilakukan terhadap larva S. litura F instar 3. Patogenesitas nematoda diukur berdasarkan mortalitas, periode letal dan virulensi. Gejala larva S. litura F yang terserang nematoda S. siamkayai menunjukkan gejala perubahan aktivitas larva yang menurun serta ukuran tubuh yang lebih kecil. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi nematoda, menyebabkan peningkatan mortalitas S. litura F, dan tidak terdapat perbedaan antara tingkat konsentrasi. Setelah 15 hari perlakuan konsentrasi 300 Ji/ml menghasilkan jumlah Ji tertinggi yakni 8915. Periode letal mencapai 11,192 hari dan virulensi 0.089.
